Abstract (en)
[origin: US2008247314A1] A policy change management scheme for network resource management through dynamic policy adaptations especially suitable for DiffServ-enabled MPLS networks is presented. The scheme incorporates automated resource adaptation capabilities to assure QoS for user traffic and to promote resource utilization in DiffServ-enabled MPLS networks. A suite of resource management policies, an ordered set of methods for adjusting policies, and interfaces to a companion policy-based network management system are provided. The policies are periodically adjusted based on predictive bandwidth estimation algorithms ensuring optimal resource allocation to individual service classes and enabling adjustment of resources for handling current traffic and traffic expected for the near future. Resource allocations to individual service classes are adapted through policy changes when bandwidth utilization deviates from normal level or congestion exists in one or more service classes, allowing corrections to abnormal allocation of resources in incipient phases of congestion.
